  • Touch location determination using vibration wave packet dispersion
    Publication number: 20060139339
    Abstract: Methods and devices provide for determination of the location of a touch on a touch plate by sensing dispersive vibrations at each of a number of vibration sensors coupled to a touch plate, the vibrations caused by the touch on the touch plate. An amount of dispersion in the dispersive vibrations sensed at each of the vibration sensors is determined. A distance between the touch and each of the vibration sensors corresponding to the amount of dispersion in the dispersive vibrations sensed at each of the vibration sensors is calculated. The touch location is determined using some or all of the calculated distances.
